What Your Neighbors Are Saying About Us

Replaced the old with the new. I got a fantastic price on the new heat pump system. The installation went really smoothly, and it is working great. I like this company.

We’ve been clients of Ellis for 20+ years at our home and office. Yesterday we woke to no heat, of course with the coldest temps of the year just 2 days away, we called Ellis.

Ellis air installed an infinity heat pump system at our home 15 years ago. Best thing we have ever done. It has preformed beautifully over the years and is still going strong thanks to Ellis Air.

Jesse came for my semi annual heating checkup. He was prompt, calling ahead to say he was on his way. He was very thorough and explained everything he did.

I highly recommend Ellis Air & Heat. Larry Hatley service Technician came out and checked the unit out. Larry is one of the most pleasant, delightful person to deal with.

What Is the Right Humidity Level for Your Home

Indoor relative humidity should stay between 30 and 50 percent for most homes. In Dallas, where outdoor humidity regularly climbs during spring and summer months, keeping indoor levels in that range requires more than just running your air conditioner. When humidity rises above 50 percent indoors, your home starts to feel stuffy and uncomfortable even when the temperature is set correctly. A properly sized dehumidifier works alongside your HVAC system to maintain that balance year-round, keeping your living space comfortable and your home protected.

Warning Signs Your Home Has Too Much Moisture

Excess moisture rarely announces itself all at once. More often, it shows up in small ways that are easy to overlook until the problem becomes serious. If you notice any of the following, your home may have a humidity problem worth addressing.

Condensation forming on windows or glass doors, especially in the morning
A musty or stale smell that lingers in certain rooms or throughout the house
Visible mold or mildew growth in bathrooms, basements, or along walls
Wood floors, trim, or cabinetry that is warping, swelling, or buckling
Feeling sticky or clammy indoors even when the air conditioning is running
Increased allergy or asthma symptoms among household members
Peeling paint or wallpaper, particularly near exterior walls

Dallas homeowners often notice these signs most during the spring and early summer, when outdoor dewpoint levels rise significantly and moisture finds its way inside through every gap and opening in the building envelope.

What Excess Humidity Does to Your Home Over Time

Left unaddressed, high indoor humidity causes damage that compounds over time. Moisture is one of the leading contributors to mold growth, and in Dallas, the warm indoor temperatures create ideal conditions for mold to spread quickly once it takes hold. Beyond mold, persistent humidity weakens structural materials, promotes pest activity, and shortens the life of your HVAC equipment by forcing it to work harder than it should. Indoor air quality also suffers as humidity feeds biological growth and increases airborne allergens. For homeowners who have invested in quality finishes and furnishings, excess moisture is a slow and costly problem that a dehumidifier can prevent entirely.

How a Dehumidifier Works

A dehumidifier integrated into your HVAC system is installed alongside your air handler or within the ductwork. As air circulates through your system, it passes through the dehumidifier, which draws out excess moisture before the conditioned air is distributed throughout your home. The collected moisture drains away automatically, and the dehumidifier operates independently of your air conditioner, meaning it can run whenever humidity levels rise — even on mild days when cooling is not needed. Most systems are controlled through your thermostat or a dedicated humidistat, giving you precise control over your indoor environment without any manual effort.

Getting a Dehumidifier Installed

The installation process starts with an assessment of your home’s size, current HVAC configuration, and moisture load. Proper sizing is critical. An undersized unit will struggle to keep up during peak humidity months, while an oversized unit can over-dry the air and create its own set of problems. Our technicians will evaluate your home, explain your options clearly, and recommend the right solution for your specific situation. We provide a straightforward proposal before any work begins so you know exactly what to expect. Installation typically involves integrating the dehumidifier into your existing ductwork and connecting it to your drainage and electrical systems. Our team handles the full installation with minimal disruption to your home, and we test the system thoroughly before we leave.

Frequently Asked Questions

How is a ducted dehumidifier different from a portable unit?

A dehumidifier integrated with your HVAC system treats air throughout your entire home automatically, while portable units only address moisture in one room at a time and require manual emptying.

Does a dehumidifier replace my air conditioner?

No. A dehumidifier works alongside your air conditioner. While your AC removes some moisture as it cools, a dedicated dehumidifier controls humidity independently and more precisely, especially on days when cooling is not needed.

What humidity level should I set my dehumidifier to?

Most Dallas homeowners find that setting their dehumidifier between 45 and 50 percent relative humidity provides the best balance of comfort and protection for their home.

How often does a dehumidifier need maintenance?

Dehumidifiers integrated with your HVAC system are relatively low-maintenance. Filters should be checked and cleaned periodically, and the unit should be inspected annually as part of your regular HVAC maintenance.

Can high humidity damage my HVAC system?

Yes. Excess moisture increases the workload on your air conditioning system, can promote mold growth inside ductwork, and may contribute to corrosion and mechanical wear over time.
